Research on High Performance Vitrified Bond Diamond Wheel

Abstract:

Two kinds of vitrified bonds, bond L (low temperature bond) and bond G (high strength bond), were blended by ball-milling in producing diamond wheels. Proper Sintering techniques were employed by analyzing properties of the wheel through DSC testing and fracture strength. The wheels were applied in machining PDC in comparison with similar product on market. It showed that the blended bond reached its highest fracture strength when bond L amount was about 20wt~24wt%; combination of this two kinds of vitrified bonds would improve the wheel’s comprehensive properties by raising its fracture strength to 89MPa when bond L takes up 22wt%; service life of wheels prepared by this blended bond was 30~50% longer than similar market product and efficiency improved by more than 20%.

Study of the Wettability between Diamond Abrasive and Vitrified Bond with Low Melting Point and High Strength

Authors: Jian Bing Zang, Jing Lu, Yan Hui Wang, Xiang Hong Zhang, Yun Gang Yuan

Abstract: The adhesion between diamond grits and the bond strongly influence the properties of diamond tools. Since diamond is covalent crystal, the high interfacial energy leads to the poor interface bonding between diamond grits and the bond. Furthermore, the sintering temperature of traditional vitrified bond is also very high because of the high refractoriness of alkalis containing in the bond, resulting in serious thermal damage to diamond grits. In this paper, a low melting point and high strength vitrified bond has been prepared mainly from borate glass, clay and lead glass. The bond is completely glassy above 850°C and the bending strength of the bond sintered at 850°C for 7 minutes is 125.7MPa with a 6.5:3.5 corundum/bond ratio. Moreover, this bond possesses good wettability with diamond abrasive from 600°C to 850°C.

The Characteristic of Organic Bond Grinding Wheel

Authors: Mei Wei Chen, Ju Long Yuan, Yi Yang, Dong Qiang Yu

Abstract: The bond in a grinding wheel cements the abrasive grains together, Among other factors, the bond plays a predominant part in the grinding wheel performances and on the quality of grinding results. This paper presents a literature review on organic bond grinding wheels. It discusses the characteristic of the bond and the grinding performances of the two mainly types of organic bond [1] grinding wheels: the resin bond grinding wheel and the soft-elastic grinding wheel. This paper provide a conclusion of the studying state of organic grinding wheel, which new studying can draw lesson from.

Abstract: Resin bond is one of the most widely bond used for manufacturing abrasive product. This review paper discusses historical perspectives on resin bond, there are different abrasive products which can be produced by using various types of resin bond such as modification of Phonetic resin and a new water-soluble resin. It is intended to help readers to gain a more comprehensive view on resin bond used for abrasive products and to be instrumental for research and development in producing abrasive products.
